8 Best Knives to Cut Carpet 2026

This no-nonsense powerhouse delivers razor-sharp precision and rugged durability in a single, purpose-built tool. The serrated, dual-honed stainless steel blade with a hollow-ground edge slices through thick carpet padding and dense vinyl like butter, while the HRC55 hardness rating means it holds its edge far longer than typical utility blades—fewer swaps, more cutting. Designed for tradespeople who demand reliability, it excels in tight corners and detailed trimming, solving the common frustration of blade drag and binding during deep cuts.

In real-world use, the 8-7/8-inch blade offers excellent reach under thresholds and along baseboards, making it ideal for flooring pros and DIYers tackling full-room installations. The curved sharp edge works seamlessly on both push and pull strokes, especially when cutting linoleum or synthetic turf, though it can struggle slightly on ultra-thick commercial-grade carpet backings. At 120 grams, it’s well-balanced, and the soft-grip handle reduces hand fatigue during extended use—even with sweaty palms—thanks to its non-slip matte texture.

Compared to retractable models like the XW or ROBERTS dual-depth knives, the Goldblatt trades adjustability for raw cutting performance and simplicity. It’s not a multi-tool, but it dominates where it matters: consistent, aggressive cutting across flexible materials. If you prioritize edge retention and ergonomic control over blade depth adjustment, this knife outperforms more complex designs at a similar price point.

Meet the precision-tuned workhorse that brings surgical control to carpet cutting with its innovative 3-position retractable blade system. This knife stands out with its twist-lock mechanism, letting users dial in exact blade exposure—a game-changer when slicing thin vinyl versus thick berber carpet, preventing accidental punctures or uneven cuts. The angled zinc alloy body and soft TPR grip ensure maximum control, making it a top pick for installers who need depth accuracy without sacrificing durability.

During installation tests, the adjustable depth feature proved invaluable when working near fragile subfloors or delicate edges, where over-penetration is a real risk. The 3mm, 6mm, and 9mm settings allow for tailored performance across materials, and the swing-open housing makes blade changes fast and tool-free—plus, the built-in storage for one spare blade keeps you ready on the job. While it handles most carpet types smoothly, the relatively short blade can require more passes on thick padding, slowing down large-area cuts.

When stacked against the ROBERTS Pro Dual-Depth, the XW offers finer incremental control but lacks blade storage capacity. It’s the ideal middle ground between simplicity and sophistication—perfect for detail-oriented users who need adaptability without the bulk of a folding or dual-function tool. For those who value depth customization and stability, this knife delivers smarter control than fixed-blade rivals at a competitive feature set.

This is the gold standard for professional carpet installers—a thoughtfully engineered tool that solves real-world problems with its patented dual-depth insert system. Designed to automatically adjust to varying carpet-back thicknesses, it ensures clean, consistent cuts whether you’re working with plush padding or commercial-grade backing. The extended tangs on the blade spindle prevent slippage, a small but critical detail that boosts safety and precision during aggressive pulls.

In practical use, the ability to switch between depth settings on the fly eliminates guesswork and reduces material waste—a major win for contractors working on tight margins. The finger indent and thumb stop provide exceptional leverage, making long straight cuts less taxing on the hand, while compatibility with both round and square-end blades increases versatility. It handles heavy-duty tasks with ease, though it lacks a protective cap, leaving the blade exposed when stored in a tool bag.

Compared to the Goldblatt and XW models, the ROBERTS Pro strikes the best balance of smart design, durability, and professional-grade functionality. It’s not the lightest or cheapest, but it’s the most complete package for serious work. If you want a knife that combines innovation with job-site toughness, this model sets the benchmark for overall performance and reliability.

Don’t let the modest price fool you—this compact, no-frills folder punches above its weight as the most budget-smart choice for occasional users and DIYers. Built with a lock-back mechanism and SK2 slotted blades, it delivers sharp, reliable cuts through standard carpet and vinyl without breaking the bank. The protective plastic cap adds a layer of safety when folded, making it ideal for toolboxes or job bags where accidental exposure is a concern.

In real-world testing, the zinc-alloy body feels solid in hand, and the anti-slip TPR grip holds firm even during push cuts across textured flooring. Blade changes are fast thanks to the slider mechanism, and the included 5 extra blades ensure long-term usability. While it lacks advanced features like depth adjustment or blade storage inside the handle, it performs admirably for basic trimming and small installations. However, it’s not built for marathon sessions—pros may find the grip less comfortable over time.

Against pricier models like the ROBERTS or XW roller knife, this one trades features for affordability and simplicity. It’s the go-to for homeowners or handymen who need a dependable, safe, and replaceable knife without over-investing. If you want solid performance at a minimal cost, this folding knife offers unbeatable value for light to moderate carpet work.

This two-in-one beast is engineered for installers who face a wide range of flooring challenges and demand maximum versatility and durability. The roller wheel on the heavy-duty knife glides effortlessly over carpet, ensuring straight, controlled cuts without gouging the subfloor—a lifesaver when trimming wall-to-wall installations. Paired with a lightweight precision knife featuring a finger guard, this set covers both aggressive cutting and delicate detailing in one package.

During testing, the roller knife excelled on thick, high-pile carpets, maintaining consistent depth and reducing hand strain thanks to its ultra-smooth wheel mechanism. The lightweight model, with its ABS plastic body and secure grip, is perfect for overhead or edge trimming where control matters most. Both knives include internal blade storage, and the bonus 15 blades (utility, hook, and carpet-specific) mean you’re rarely without a sharp edge. However, the roller mechanism can clog with dense fibers if not cleaned regularly.

Compared to single-function knives like the Goldblatt or Cal Hawk, this 2-pack offers unmatched range and readiness. It’s heavier than minimalist options, but that’s the trade-off for dual-role performance. If your work involves both heavy-duty and precision tasks, this set delivers more capability than any single knife in its class.

This dual-function marvel redefines utility with a clever two-in-one design that cuts carpet on one end and jams it into gullies on the other—eliminating the need to switch tools mid-job. The die-cast aluminum body is rugged yet lightweight, and the checkered handle delivers a slip-resistant grip even in dusty or damp conditions. For installers who regularly stretch and secure carpet edges, this knife saves time and streamlines workflow like no other.

In practice, the cutting end handles standard carpet with ease, while the jamming end fits perfectly into threshold grooves, allowing you to tuck edges cleanly without a separate tool. The safety thumb guard and blade cover add protection during use and storage, and the handle stores up to 10 spare blades—three are included. While the blade isn’t as long as some competitors, limiting reach on wide cuts, its dual-purpose nature more than compensates for minor reach limitations.

Against single-task knives like the BIBURY or XW folders, this ROBERTS model wins on functional innovation. It’s not the sharpest or lightest, but it’s the most job-smart tool for carpet stretchers and finishers. If you want two essential functions in one durable body, this knife offers smarter workflow integration than any other in the lineup.

Engineered with safety and convenience in mind, the BIBURY utility knife is a smart upgrade for users who want a reliable, multi-material cutter that won’t compromise on protection. The metal blade-release button and safety lock ensure the blade stays secure during use and storage, while the plastic tip protector prevents accidental punctures—a rare but crucial feature in carpet knives. Its anodized aluminum body resists corrosion and wear, making it a durable companion for both indoor and outdoor jobs.

In real-world use, the widened grip fits comfortably in all hand sizes, reducing fatigue during repetitive cuts across carpet, cardboard, or plastic sheeting. The 10 included SK5 stainless steel blades stay sharp through multiple tasks, and the belt clip adds portability for mobile workers. While it performs well on standard carpet, the straight blade isn’t optimized for pull-cutting thick padding like a hook-style knife, limiting its effectiveness for full flooring installs.

Compared to the Goldblatt or XW models, the BIBURY shines as a general-purpose cutter with superior safety features, not a specialized carpet knife. It’s best suited for handymen, janitors, or contractors who need one tool for multiple light-duty tasks. If safety, blade longevity, and multi-use flexibility are your priorities, this knife outperforms single-role competitors with thoughtful design touches.

This featherlight contender is a revelation for users who prioritize agile handling and quick access over brute strength. Weighing next to nothing thanks to its cast aluminum body with non-slip coating, it’s the easiest knife in the lineup to carry all day without hand strain. The pivoting handle opens fully for instant blade access or storage, making swaps fast and simple—no tools, no fuss.

In practice, the lightweight design makes it ideal for overhead cuts, stair installations, or tight spaces where wrist movement is limited. The thumb knob allows one-handed opening, a small but appreciated feature when working with gloves. While it lacks the heft for deep cuts in commercial carpet, it handles residential-grade materials with ease. However, the minimal handle design offers less grip security during forceful pulls, increasing slip risk on wet surfaces.

Versus heavier models like the ROBERTS Pro or XW roller knife, the Cal Hawk trades power for nimbleness and portability. It’s not built for marathon installs, but it’s perfect for quick fixes, touch-ups, or mobile technicians who value speed and ease. If lightweight maneuverability and fast blade access matter most, this knife delivers where it counts—especially for on-the-go professionals.
